The full range, Quinacridone Rose to Chromium Oxide Green
Ratios are parts by volume, the way you would put them out on a palette.
These two knock each other back a long way without quite cancelling. The middle of the range is a muted, slightly colored gray — often more useful than a dead neutral, because it still belongs to the painting around it.
The quietest point: #614A3F
At 1:6 this pair is at its most neutral. That is the mixture to reach for when you need a shadow or a gray that still belongs to the rest of the painting.
The same range with white added
Two parts titanium white to one part of the mixture above. White lifts the value but also takes the chroma down, which is why a tint is never simply a lighter version of the same color.
The same range as a watercolor wash
Roughly one part paint to two parts water, over white paper. Remember that watercolor dries up to about thirty per cent lighter than it looks while wet.
Quinacridone Rose is much the stronger of the two. The ratios above are by volume, so the first step away from pure Quinacridone Rose already changes a lot less than the last step towards it. Put out less than looks right and work towards the color; going back costs far more paint.
What you are working with
| Pigment | Index | Strength | Opacity | Lightfast | In |
|---|---|---|---|---|---|
| Quinacridone Rose | PV19 | 9/10 | transparent | excellent | Oil, Watercolor |
| Chromium Oxide Green | PG17 | 5/10 | opaque | excellent | Oil, Watercolor |
Very strong. A sliver is enough. Use it as your primary red in a split-primary palette.
A dull, opaque green. Close to the color of a lot of real foliage.
